如何在春季 MVC 中配置测试

Question

如何在Spring mvc中配置测试？ 基于 Java 的配置。

这是我的用户测试类

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = {
HibernateUtils.class }, loader = AnnotationConfigContextLoader.class)
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
DbUnitTestExecutionListener.class })
public class UserDaoTest {
@Autowired
private UserService userService;
@Autowired
private RoleService roleService;

我的应用程序有三个配置文件。

HibernateUtils.java

@Configuration
@EnableTransactionManagement
@ComponentScans(value = { @ComponentScan("com.example.packages") })
public class HibernateUtils {
@Autowired
private ApplicationContext context;
@Bean
public LocalSessionFactoryBean getSessionFactory() {
LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
factoryBean.setConfigLocation(
context.getResource("classpath:hibernate.cfg.xml"));
factoryBean.setAnnotatedClasses(User.class);
factoryBean.setAnnotatedClasses(Role.class);
return factoryBean;
}

@Bean
public HibernateTransactionManager getTransactionManager() {
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(getSessionFactory().getObject());
return transactionManager;
}

}

网络配置.java

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "com.example.package" })
public class WebConfig implements WebMvcConfigurer {
@Override
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.jsp().prefix("/WEB-INF/pages/").suffix(".jsp");
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new HomePageFilter()).addPathPatterns("/");
registry.addInterceptor(new EncodingFilter()).addPathPatterns("/*");
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
registry.addViewController("/create").setViewName("createUser");
registry.addViewController("/user").setViewName("user");
registry.addViewController("/admin").setViewName("admin");
registry.addViewController("/edit").setViewName("editUser");
registry.addViewController("/remove").setViewName("remove");
registry.addViewController("/logout").setViewName("logout");
registry.addViewController("/error").setViewName(" unauthorized");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("/resources/");
}
@Bean
public MessageSource messageSource() {
ResourceBundleMessageSource source = new ResourceBundleMessageSource();
source.setBasename("messages");
return source;
}
}

网络初始化

public class WebMvcApplicationInit
extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { WebSecurityConfig.class,
HibernateUtils.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { WebConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}

毕竟。 我的测试抛出异常

如何设置 ServletContext？ 我在用户测试类中设置了什么？ 冬眠工作得很好。

Answer 1

你应该改变

@ContextConfiguration(classes = {
HibernateUtils.class }, loader = AnnotationConfigContextLoader.class)

上

@ContextConfiguration(classes = {
HibernateUtils.class }, loader = AnnotationConfigWebContextLoader.class)
